Solar power station

ABSTRACT

A solar power station includes a plurality of solar panels each connected to a leaf, the leaf including a roof beam; a plurality of bearing plates respectively attached to the roof beams of the leaves; a first supporting structure connected to the bearing plates; a second supporting structure rotatably connected to the first supporting structure and fixedly mounted to a base; and a plurality of hydraulic jacks. One end of each hydraulic jack is fixed with the first supporting structure, and another end of the hydraulic jack is pivotally mounted to the roof beam of one of the leaves.

TECHNOLOGY FIELD

The present patent application generally relates to solar power systemsand more particularly to a solar power station for accurately pointing asolar panel at the sun throughout the day that has good structuralstrength and flexibility.

BACKGROUND

A typical solar power station includes a solar tracking system employingtwo independent drives to tilt the solar collector about two axes. Thefirst, an elevation axis, allowed the collector to be tilted within anangular range of about ninety degrees between “looking at the horizon”and “looking straight up”. The second, an azimuth axis, is required toallow the collector to track from east to west. The required range ofangular rotation depends on the earth's latitude at which the solarcollector is installed. For example, in the tropics the angular rotationneeds more than 360 degrees.

The heavy elements of the solar power station normally require a strongsupporting structure to withhold the weight of the solar power station,and a relatively large force to turn the solar power station around. Inaddition, the solar power station needs to be able to withstand possibleearthquake shocks and wind attacks in an outdoor environment.

SUMMARY

The present patent application is directed to embodiments of a solarpower station. The solar power station includes a plurality of solarpanels each connected to a leaf, the leaf including a roof beam; aplurality of bearing plates respectively attached to the roof beams ofthe leaves; a first supporting structure connected to the bearingplates; a second supporting structure rotatably connected to the firstsupporting structure and fixedly mounted to a base; and a plurality ofhydraulic jacks. One end of each hydraulic jack is fixed with the firstsupporting structure, and another end of the hydraulic jack is pivotallymounted to the roof beam of one of the leaves.

DETAILED DESCRIPTION

Reference will now be made in detail to embodiments of the solar powerstation in the present patent application, examples of which are alsoprovided in the following description. Exemplary embodiments of thesolar power station disclosed in the present patent application aredescribed in detail, although it will be apparent to those skilled inthe relevant art that some features that are not particularly importantto an understanding of the solar power station may not be shown for thesake of clarity.

Furthermore, it should be understood that the solar power stationdisclosed in the present patent application is not limited to theprecise embodiments described below and that various changes andmodifications thereof may be effected by one skilled in the art withoutdeparting from the spirit or scope of the protection. For example,elements and/or features of different illustrative embodiments may becombined with each other and/or substituted for each other within thescope of this disclosure.

FIG. 1A is a front view of a solar power station according to anembodiment of the present application. Referring to FIG. 1A, the solarpower station includes a plurality of leaves 1 and a plurality ofsupporting plates 2 for respectively supporting the weight of aplurality of solar panels. Each leaf 1 is connected with a plurality ofsolar panels and spaced from one another. The top surface of eachsupporting plate 2 is connected to a horizontal roof beam 88 of eachleaf 1. The bottom surface of each supporting plate 2 is connected to apair of bearing plates 3. A plurality of shafts 5 are respectivelypivotally mounted to each pair of the bearing plates 3. A plurality ofsteel washers 4 and a shock absorption pads 6 are respectively placedbeside each bearing plate 3. Each steel washer 4 is locked beside eachshaft 5 and configured to prevent the corresponding bearing plate 3 fromfalling off from the shaft 5. The shock absorption pads 6 are configuredto absorb shock for the bearing plate 3 during an earthquake. The shafts5 are respectively connected to multiple beams 7, which are connected toa cross structure as shown in FIG. 1A. The cross structure has a sidetruss 8 for supporting the weight of loading transferred from the beams7. The supporting plate 2, the bearing plate 3, the steel washer 4 andthe shaft 5 form a unit. A plurality of such units are respectivelyconnected through the beams 7 so that the loading of a top roof istransferred to the beams 7. The units are respectively connected to aplurality of vertical roof beams 87 and a plurality of horizontal roofbeams 88. The horizontal roof beams 88 are configured to connect andmount the vertical roof beam 87. The loading of the solar panel istransferred from the beams 7 to a vertical pole 9 of the crossstructure. The vertical pole 9 extends through a rotatable platform 14and stands at a rotatable plate 17. Gusset plates 15 and 16 arerespectively welded to the rotatable platform 14 and the rotatable plate17. The vertical pole 9 is fixed to the rotatable plate 17 by bolt andnut assemblies, and the rotatable plate 17 is connected to a rotatablebearing 40 by bolt and nut assemblies (shown in FIG. 2A), which will bedescribed in more detail hereafter.

Referring to FIG. 1A, the solar power station further includes astanding pole 20. An upper part of the standing pole 20 is covered by acircular hoop 19. A first end of the standing pole 20 is connected tothe rotatable platform 14 through the rotatable bearing 40 (shown inFIG. 2A and described more in detail hereafter). A second end of thestanding pole 20 is inserted into a shock absorbing pole 25. The shockabsorbing pole 25 is fixed by a standing plate 26, which is anchored toa base, such as the ground (or soil).

Referring to FIG. 1A, the solar power station further includes ahydraulic jack 10. A first end of the hydraulic jack 10 is fixed to abearing plate 11 disposed on the rotatable platform 14. A shaft 13 isdisposed passing through the bearing plate 11 and the first end of thehydraulic jack 10. A washer and bolt assembly 12 is used to lock theshaft 13 and prevent it from moving. A second end of the hydraulic jack10 is connected to a sitter 51 (not shown in FIG. 1A but shown in FIGS.5A and 5B) of each leaf 1 and configured for mounting an array of thesolar panel. A plurality of hydraulic jacks 29 are respectivelyconnected to the sitter 51 of each leaf 51. The details of the fixing ofthe hydraulic jacks 29 are shown in FIGS. 9A to 9E and FIGS. 10A to 10E.

The solar power station in this embodiment further includes lightsensors 53, 80 and 81 disposed at different locations of the verticalroof beam 87 as illustrated in FIG. 1A. The light sensors 53, 80 and 81respectively include a photoresistor, which changes resistance accordingto incident light intensity. In this embodiment, the light sensors 53,80 and 81 are electrically connected to a microprocessor and configuredfor transmitting signals thereto, thereby enabling basic automatic suntracking operations for the solar power station.

The light sensor 53 includes two smaller light sensors. Referring toFIG. 1A, the two smaller light sensors are configured to compare theintensities of the incident light on the left and right of the top (orbottom) of the solar panel roof. If the solar panel is facing righttowards the sun, both of the two smaller light sensors are getting thesame light intensity so that the difference therebetween is zero and thedrive voltage of a tracking motor included in the system (which will bedescribed in more detail hereafter) is zero. In this case, the systemhas tracked the current position of the sun. After some time, as theearth rotates, the solar panel gets repositioned with respect to thesun, and the smaller light sensor at one side gets less light intensitythan the other one. In this case, the different light intensity readingsare sent to the microprocessor and the microprocessor is configured todrive the tracking motor with a non-zero driving voltage correspondingto the different so that the tracking motor rotates the solar panel tillthe solar panel is positioned right towards the sun again. Suchself-adjustment process goes on during the day and ensures correcttracking of the solar panel to the sun.

In this embodiment, the light sensor 80 is disposed at the east edge ofthe solar panel and configured to operate as a nighttime fault detector.If a general fault occurs during nighttime then the next morning thesolar panel will not work. At the next sunrise, the sensor 80 detectswhether the solar panel is ready for tracking operation or not. Innormal conditions, the sensor 80 does not work because it gets lesslight intensity as compared to the light sensors 53 and 81. As a faultarises, it starts working.

The light sensor 81 is disposed at an opposing edge of the solar panelwith respect to the light sensor 80, and configured to detect theoccurrence of a cloudy weather. When the weather gets cloudy, the lightsensor 81 starts to work and stops normal sun tracking operation.

It is understood the light sensors 80 and 81 respectively detects thecoming of night and cloudy weather by comparing the light intensity theyreceive with the light intensity they would receive in a sunny day. Thelight intensity for the cloudy day is less than for the sunny day andgreater than for the night. It is also understood that being capable ofsensing a change in light intensity in the cloudy weather, which is asmaller change than that in the nighttime, the light sensor 81 is moresensitive than the light sensor 80.

FIG. 1B is a partial front view of a solar power station according toanother embodiment of the application. In this embodiment, referring toFIG. 1B, a bearing bracket 27 is used to maintain the supporting plate2, the bearing plate 3, the steel washer 4 and the shaft 5 together as aunit disposed on the beam 7. Each unit functions essentially the same asthe unit illustrated in FIG. 1A, except that in this embodiment, anincreased number of leaves 1 are connected to each unit and the shaft 5is disposed at a distance to the beam 7.

FIG. 2A is a partial cross-sectional view of the solar power stationillustrated in FIG. 1A. Referring to FIG. 2A, the rotatable bearing 40includes a stationary outer race fixed to the upper part of the standingpole 20. An inner gear is rotatably geared with an inner race that isconnected with the bearing plate 17 by bolts and nuts. As a safetyfeature, if the rotatable bearing 40 breaks, the circular hoop 19prevents the upper portion of the solar power station from falling down.The circular hoop 19 is connected to an outer ring of the rotatableplate 17 by bolt and nut. A circular plate 46 is welded to a first endof the upper part of the standing pole 20 so as to lock the circularhoop 19 and prevent the upper structure from falling down. A trackingmotor 45, which is connected to a reducer 44, is disposed near a firstend of the standing pole 20. In this embodiment, the tracking motor 45and the reducer 44 are disposed inside the standing pole 20. A motorshaft 43 of the tracking motor 45 is engaged with the gear 42. The gear42 is configured to rotate clockwise or anti-clockwise about a z-axisthat is parallel to the center axis of the standing pole 20 so as torotate the inner gear accordingly.

The lower part of the upper portion of the standing pole 20 has multiplerecessive tracks and multiple narrow tubes 21 are inserted into therecessive tracks. The lower part of the upper portion of the standingpole 20 is further inserted into the shock absorbing pole 25, which willbe described in more detail hereafter and also shown in FIG. 3A, FIG. 3Band FIG. 3C.

The shock absorbing pole 25 includes a hoop 22 for holding the standingpole 20 and the narrow tube 21. The narrow tube 21 is exactly engagedwith a track 36 of the hoop 22 and the shock absorbing pole 25. Theconnection of the hoop 22 and the shock absorbing pole 25 are made by abolt and nut assembly, which connects an upper circular flange 23 on thehoop 22 and a lower circular flange 24 on the shock absorbing pole 25. Alower spring 32 is placed into the shock absorbing pole 25 before thehoop 22 is connected to the shock absorbing pole 25. An upper spring 34is placed into the standing pole 20 before the standing pole 20 isconnected to the rotatable bearing 40 and before hoop 22 is connected tothe shock absorbing pole 25. A circular separation plate 31 is disposedbetween the upper spring 34 and the lower spring 32 so as to dividethem. If an external force or shocking force greater than what thespring 34 alone can react with is exerted on the spring 34, the reactionof the spring 34 will push the separation circular plate 31 and thespring 32 downward, and a potential energy will be stored in the spring32. When the spring 32 rebounds, it will be extended more than it wouldnormally be so as to release the potential energy. The upper spring 34will then absorb the released energy so that the impact of the externalforce is reduced and the solar power station will be protected frombeing damaged.

FIG. 2B is a partial cross-sectional view of a solar power stationaccording to yet another embodiment of the present application.Referring to FIG. 2B, in this embodiment, the tracking motor 45 and thereducer 44 connected thereto are installed at the outside of thestanding pole 20. An inner race is fixed to the first end of thestanding pole 20. An outer race with outer gear rotatably engaged withthe inner race is connected with the rotatable plate 17 and carrying theupper structure. It is noted in this embodiment, the locking structureincluding the circular hoop 19 and the circular plate 46 is eliminated.

FIG. 2C is a partial cross-sectional view of a solar power stationaccording to still another embodiment of the present application. In theembodiment illustrated in FIG. 2A, the second end of the vertical pole 9is fixed to the bearing plate 17. In the embodiment illustrated by FIG.2C, however, as another measure to prevent the rotatable bearing 40 frombreaking, the upper part of the standing pole 20 is inserted into thehollow circular vertical pole 9 from one end to another, which has agreater diameter than that of the standing pole 20. The upper end of thevertical pole 9 has a cross structure. Referring to FIG. 2C, the outeredge of a bearing plate 17 with a gusset plate 93 is welded to the innersurface of the first end of the hollow circular vertical pole 9 at aposition close to where the second end of the beam 7 and the verticalpole 9 location are connected, so as to withstand to the tension causedby the loading, or the compressing force exerted by the two wings of thebeam 7 caused by the top roof and the solar panel loading. In thisembodiment, a contact ball slewing ring 40, which functions as an outerrace, is connected to an outer flange 41 of the upper end of the hollowcircular standing pole 20 and rotatably engaged with an inner gearcarrying the upper structure. The hollow circular standing pole 20 isfilled with reinforcing concrete 164. The inner gear is connected withthe bearing plate 17 of the upper part of the vertical pole 9 by boltand nut. For protection in a raining weather, a steel cap 94 is coveredon the top of the hollow circular vertical pole 9 and fixed thereon bybolts and screws, by which raining water can be prevented from flowinginto the vertical pole 9.

Referring to FIG. 2C, a row of track rings 90 are evenly welded andfixed onto the outer surface of the standing pole 20, or alternativelyonto the inner surface of the vertical pole 9. The track rings 90 areseparated by a short distance from one to another. The second end of theside truss 8, which is connected to the hollow circular vertical pole 9,exerts a loading force pushing the vertical pole 9. Thus the track rings90 and the bearings 91 should be placed close to the second end of sidetruss 8 to withstand this pushing force. The bearings 91, which arerespectively hold by the track rings 90, are for example cylindricalroller bearings, ball bearings, or flange bearings, so that when thestanding pole 20 rotates inside the vertical pole 9, the frictiontherebetween can be reduced and the distance between the outer surfaceof the standing pole 20 and the inner surface of the vertical pole 9 canbe kept uniform and constant along the z axis.

The connection between the tracking motor 45 and the reducer 44 as wellas the installment of the tracking motor 45 and the reducer 44 onto thestanding pole 20 in this embodiment is the same as the embodimentillustrated in FIG. 2A. The installment of the beam 7 and the side truss8 onto the vertical pole 9 will be described in more detail with theillustration of FIGS. 10A-10D. It is noted in this embodiment, gussetplates 15 and 16 are respectively welded between the rotatable platform14 and the second end of the vertical pole 9 so as to provide amechanical support. Unlike the embodiment illustrated in FIG. 1A, inthis embodiment, gusset plates 15 and 16 are not welded to the rotatableplate 17.

The shape of the pipe 159 is suitable forinternal pipe 160 to rotate. The bottom of the bigger cylinder pipe 159is sealed and surroundingly enclosed. The inside of the bigger cylinderpipe 159 is filled with high density, low reactivity and low viscosityliquid 162, for example, water. The water level depends on the weight ofthe liquid per volume, the weight of the buoyant object, the volume ofthe external shape 159 and the internal volume of the internal pipe 160.A thin layer of low reactivity oil floats on and covers the surface ofthe pure water so as to prevent water evaporation.

The purpose of the water based buoyant method is to reduce the motorturning force. To the balance the water level within the external biggercylinder 159, the liquid 162 comes from incoming water pipe 173 when asensor senses the water level decreases within the bigger cylinder 159.If the sensor senses the water level increases within the biggercylinder 159, a suction pump is configured to suck water from thecylinder 159 to the outside through an outgoing water pipe 176.

The internal pipe 160 is contained in the cylinder pipe 159. The pipe160 connects the vertical pole 9 to the fluid. The total loading ofcross structure with vertical pole 9 is uplifted by the bigger cylinder160 or any three-dimensional shape pipe 160 and the lower part of thevertical pole 9. The ground soil 153 can cover the external pipe 159, oralternatively, the external pipe 159 can be exposed out of the groundsoil 153, depending on how strong the foundation needs to be.

The upper part of the vertical pole 9 carries the cross structure as thevertical pole 9's loading. The lower part of the vertical pole 9continuously passes through the standing pole 20 from the first end tothe second end. A plurality of track rings 90 are fixed onto the outersurface of the vertical pole 9. Alternatively, the track rings 90 arefixed onto the inner surface of the standing pole 20 behind the circulartable ring plate 139. A bearing 91 is disposed on each of the trackrings 90 to contact outer surface of the vertical pole 9 and the innersurface of the standing pole 20. The first track ring 170 includes tworings fixed onto the top end of the upper part of the inner surface ofthe standing pole 20. A bearing 91 is disposed between the two rings.The second track ring 171 also includes two rings fixed onto the outersurface of the vertical pole 9 at a short distance behind the firsttrack ring 170. A bearing 91 is disposed between the two rings. Thesecond elastic spring 169 is fixed onto the top of the second track ring171. A flange bearing 168 or thrust bearing 168 is fixed to the bottomof the first track ring 170.

Referring to FIG. 2H, the stiffener gusset plate 150 is fixed to thesecond end of the vertical pole 9 so as to increase the hardness of theflange. The stiffener gusset plate 150 strongly supports the flange,which is covered and sealed by the steel cone shape 163. The oil proofplastic ring 156 is disposed between the bigger stiffener gusset plateflange 150 of the second end of the lower part of the vertical pole 9and the top flange 158 of the upper end of the bigger cylinder pipe 160,or any three-dimensional shape pipe 160, and fixed by bolts and nuts157. The shape of the pipe 160 is suitable for internal rotation. Thebottom of the bigger cylinder pipe 160 is sealed and surroundinglyenclosed. The inside of the bigger cylinder pipe 160 is empty or filledwith foam and near to the bottom of the vertical pole 9 is sealed by asteel plate 165. On the other end of the steel plate 165, reinforcingconcrete 164 is filled inside the vertical pole 9. The lower part of thebigger cylinder pipe 159 has two openings 190, each of which is equippedwith a pipe 191 connected thereto. The pipe 191 is configured forconnecting the opening 191 of this solar power station to acorresponding opening of another solar power station (not shown in FIG.2H) according to this embodiment, for example, a solar power stationthat is adjacent to this solar power station. By liquid pressureprinciples, the liquid 162 can be transferred between the biggercylinder pipes 159 of a plurality of solar power stations and therebythe level of the liquid 162 in the plurality of solar power stations canbe balanced.

FIG. 2I is a partial cross-sectional view of a solar power stationaccording to still another embodiment of the present application.Referring to FIG. 2I, the solar power station is similar to the solarpower station depicted in FIG. 2H except in this embodiment, the turningsystem which includes the motor 45, the reducer 44, the gear 42 and theextending ring gear 98, is replace by a turning screw system, in whichthe vertical pole 9's z axis is applied with the buoyant force of liquid162, which is equipped with the incoming water pipe 173 and the outgoingwater pipe 176 as shown in FIG. 2I.

The turning screw system operates on turning the screws, which includesbolt fastening or nut loosing. Each bolt or nut has a thread and eachthread has a top face and a bottom face. The nut is similar to theexternal shell hoop 161, which includes the internal thread 195 beinghelically or spirally turning around and attached from the bottom to thetop of the internal surface of the external shell hoop 161. The pitch ofthe thread (the distance from one thread to the next thread) of shellhoop 161 is bigger than a normal screw thread pitch. The bolt is alsosimilar to the vertical pole 9, which includes the external thread 196helically or spirally turning around and attached from the lower part tothe intermediate position of the external side of the vertical pole 9above the top ring plate 139. Similarly, the pitch of the thread 196 isbigger than normal screw.

For easy turning, a row of ball bearings 198 are disposed onto the topsurface of the internal thread 195 of the external shell hoop 161 andthe bottom surface of the external thread 196 of the vertical pole 9.Another row of ball bearings 197 are disposed onto the top surface ofthe external thread 196 of the vertical pole 9 and the bottom surface ofthe internal thread 195 of external shell hoop 161.

Referring to FIG. 2J and FIG. 2K, the long bolt 205 passes through theupper end of the external thread 196 of the vertical pole 9, which isfixed by the nut and screw at the external thread 196. The blocker 199is fixed at the bottom end of the external thread 196 of the verticalpole 9 to store and push the ball bearings 197 and 198 to rotate alongthe internal thread 195 of the external shell hoop 161.

Referring to FIG. 2J, the bottom of the blocker 199sits on the top the plate 139 and the top of external thread 196 of thevertical pole 9 near to an intermediate position of the external shellhoop 139. The vertical pole 9's buoyancy upward level follows the waterlevel change within the external bigger cylinder 159. When the water isincreased by an external pump and through the incoming water pipe 173,as shown in FIG. 2K, the buoyancy force pushes the vertical pole 9upwards and changes the resultant vertical upward force into upwardclockwise rotation force 212. This results in the blocker 199 and thebottom of the external thread 196 rotating gradually clockwise as shownin the arrow 212, along the internal thread 195 from the bottom to theintermediate position of the external shell hoop 139, and the topexternal thread 196 rotation turning 212 which follows the internalthread 195 from intermediate to the top of external shell hoop. Thebearings 197 and 198 follow the turning. When the water level isdecreased by a suction pump and an outgoing water pipe 176 withdrawingthe water, the vertical pole automatically downwardly and graduallyrotates counter-clockwise in the direction of 213 turning to theoriginal position. Finally the blocker 199 sits on the top of the plate139.

Referring to FIG. 3A, thelower part of the standing pole 20 has a plurality of recessive tracks28. A plurality of narrow tubes 21 are respectively inserted into thetracks 28 and fixed by bolts and nuts 35, or alternatively welded withthe surface of the standing pole 20. In the assembly process, the lowerpart of the standing pole 20 with the projecting narrow tubes 21 isfirst inserted into the upper part of the hoop 22. Then the narrow tubes21 are inserted into the track 36 between the standing pole 20 and thehoop 22.

FIG. 3B is a partial cross-sectional view of the solar power illustratedin FIG. 2A taken along line 3 b in FIG. 2A. In particular, FIG. 3Billustrates a cross-sectional view of the hoop 22 and the upper part ofthe shock absorbing pole 25. Referring to FIG. 3B, in this embodiment, aspring 34, instead of the track 36, is inserted into the gap between thestanding pole 20 and the hoop 22 before the circular plate 31 and lowerspring 32 are inserted into the gap between the lower part of thestanding pole 20 and the upper part of the shock absorbing pole 25. Theupper part of the shock absorbing pole 25 has a thick wall so as tosupport the spring 32.

FIG. 3C is a partial cross-sectional view of the solar power illustratedin FIG. 2A taken along line 3 c in FIG. 2A. In particular, FIG. 3Cillustrates a cross-sectional view of the lower part of the shockabsorbing pole 25. Referring to FIG. 3C, the lower part of the standingpole 20 has a plurality of recessive tracks 28. The standing pole 20further has a plurality of narrow tubes 21 respectively inserted intothe tracks 28 and fixed by bolts and nuts 35, or alternatively weldedwith the surface of the standing pole 20. The lower part of the standingpole 20 with projecting narrow tubes 21 is inserted into the lower partof the shock absorbing pole 25.

FIG. 4A illustrates a solar power station under an upward external forceaccording to still another embodiment of the present application. FIG.4B illustrates the solar power station illustrated in FIG. 4A under adownward external force. Referring to FIG. 4A and FIG. 4B, the hoop 22is connected with the shock absorbing pole 25 through an upper circularflange 23 and a lower circular flange 24 by bolts and nuts. The lowerspring 32 is disposed into the shock absorbing pole 25 and the upperspring 34 is disposed into the standing pole 20 before the standing pole20 is connected to the rotatable bearing 40. The separation circularplate 31 is disposed between the lower spring 32 and the upper spring 34so as to divide them.

Under normal conditions, i.e., when no external forces are applied tothe solar power station, the gravity force of structure itselfcompresses the lower spring 32 downwards through the circular plate 31and the lower spring 32 reacts with an upward spring force to maintainitself in a balanced position. Referring to FIG. 4 a, if an upwardexternal force 37, for example, caused by an earthquake, is applied tothe structure, the circular plate 31 along with the standing pole 20will push the upper spring 34 upwards and compress the upper spring 34to store energy. Referring to FIG. 4B, if a downward external force 38,for example, caused by an earthquake, is applied to the structure, theforce will bring the loading and circular plate 31 together to compressthe lower spring 32 to store energy. The lower spring 32 will thenrebound and be extended more than it would normally be so as to releasethe energy. The narrow tubes 21 stay in the tracks 36 as shown in FIG.3A in this process. Since the upper spring 34 absorbs the energyreleased by the lower spring 32, the impact of the external force isreduced and thereby the damage to the solar power station can beavoided.

FIG. 5A illustrates a solar power station in one working mode accordingto still another embodiment of the present application. FIG. 5Billustrates the solar power station illustrated in FIG. 5A in anotherworking mode. FIG. 5C is a partial perspective view of the solar powerstation illustrated in FIG. 5B. In particular, FIG. 5A, FIG. 5B and FIG.5C illustrate how the solar power station rotates. Referring to FIG. 5A,the solar power station is a solar tracking machine designed to rotateabout two axes. The first axis is the x axis, which is parallel to theshaft 4. If the hydraulic jack 10 extends or withdraws the shaft 52, thetop roof of the solar panel will rotate anticlockwise (as shown by thearrow 57) and clockwise (as shown by the arrow 58) about the x axisrespectively. The second axis is the z axis, which is parallel to thecenter axis of the standing pole 20. Referring to FIG. 5C, when thetracking motor 45 drives the rotatable platform 40 (as shown in FIG. 2A)to rotate, a space truss 50 of the cross structure and the top roof ofthe solar panel will rotate anticlockwise (as shown by the arrow 55) orclockwise (as shown by the arrow 56) about the z axis (parallel to theground). Referring to FIG. 5B, a vertical beam 87 of the top roofsupports the loading and transfers the loading to the space truss 50 ofthe cross structure. The horizontal pad 59 is attached on top of spacetruss 50 to maintain the top roof of the solar panel near the horizontalposition.

FIGS. 6A-6G illustrate different types of the trusses used by the solarpower station according to the present application. A truss is astructure including slender members joined together at their ends. Themembers commonly used in construction include wooden struts, metal bars,angles, channels and so on. The joint connections are usually formed bybolting or welding the ends of the members to a common plate, called agusset plate, as shown in FIG. 6D and FIG. 6E, or simply by passing alarge bolt or pin through each of the members. Planar trusses lie in asingle plane and are often used to support roofs and bridges.

FIG. 6A illustrates a truss structure of a solar power station accordingto still another embodiment of the present application. Referring toFIG. 6A, the supporting crossing structure uses a multi-connected spacetruss including members 52 jointed together at their ends to form astable three-dimensional structure. Under loading and externaldisturbances such as wind, maintaining the mechanical stability of thestructure requires that the truss is kept in force and angular momentumequilibrium about all axes.

FIG. 6B illustrates a truss structure of a solar power station accordingto still another embodiment of the present application. Referring toFIG. 6B and FIG. 6D, the supporting crossing structure 50 is a trianglespace truss forming a tetrahedron, each side of which is formed by sixmembers. Each member has fours joints, adding another tetrahedronconnected to form a multi-connected tetrahedron. The center truss member80 is shared to reduce one side of the common members when sides arecombined together, or to extend the width of the shared truss member, ifthe diameter of the vertical pole 9 is large. The space truss beingfixed to the vertical pole 9 is very effective in supporting the loadingof the top roof of the solar panel.

Under loading and external disturbances such as wind, maintaining themechanical stability of the structure requires that the truss is kept inforce and angular momentum equilibrium about all axes. Other advantagesinclude that the structure reduces bearing loading at the rotatableperform 40 and reduces energy consumed by the tracking motor. Theseadvantages can be realized provided the joined members at a connectionintersect at a common point. FIG. 6E illustrates how the pins and thegusset plates are joined together in this embodiment.

FIG. 6C illustrates a truss structure of a solar power station accordingto still another embodiment of the present application. Referring toFIG. 6C, a compound truss is formed by connecting two or more simpletrusses 7 and 8 together. Quite often this type of truss is used tosupport loads having large dimensions, since it is cheaper to constructvery light compound truss. FIG. 6D shows how the pins and the steelframe are joined together to form the truss structure in thisembodiment.

FIG. 6E illustrates a truss structure of a solar power station accordingto still another embodiment of the present application. Referring toFIG. 6E, in this embodiment, the truss structure is similar to the trussstructure illustrated in FIG. 6C except a steel wire or side truss 151is connected between a top end of the vertical pole 9 and the horizontalbeam 7.

FIG. 6F illustrates a truss structure of a solar power station accordingto still another embodiment of the present application.
